Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42436, here are decompositions:

  • 3 + 42433 = 42436
  • 29 + 42407 = 42436
  • 113 + 42323 = 42436
  • 137 + 42299 = 42436
  • 179 + 42257 = 42436
  • 197 + 42239 = 42436
  • 227 + 42209 = 42436
  • 239 + 42197 = 42436

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42436 first appears in π at position 68,892 of the decimal expansion (the 68,892ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
